Abstract

An image forming apparatus includes an image-carrying component configured to carry a colorant image including an adjustment image, a transferring component having a recess in an outer peripheral surface and configured to transfer the colorant image from the image-carrying component to a recording medium in a transfer area while rotating in such a manner as to allow a retainer that is retaining the recording medium to pass through the recess, an image-forming component configured to form the adjustment image at such a position of the image-carrying component as to face the recess of the transferring component, and a transporting component configured to cause the recording medium retained by the retainer to pass through the transfer area.

First claim

What is claimed is:

1. An image forming apparatus comprising:
an image-carrying component configured to carry a colorant image including an adjustment image;
a transferring component having a recess in an outer peripheral surface and configured to transfer the colorant image from the image-carrying component to a recording medium in a transfer area while rotating in such a manner as to allow a retainer that is retaining the recording medium to pass through the recess;
an image-forming component configured to form the adjustment image at such a position of the image-carrying component as to face the recess of the transferring component; and
a transporting component configured to cause the recording medium retained by the retainer to pass through the transfer area, wherein
the retainer that is transporting the recording medium while retaining a leading end of the recording medium is configured to be received by and come out of the recess of the transferring component,
the retainer is attached to the transporting component and is configured to go into the recess while the transporting component is moving,
the adjustment image is formed at such a position of the image-carrying component as to face the recess with the retainer being positioned in the recess, and
the image-forming component is configured to form the adjustment image to overlap with an area of the recess excluding areas where the retainer is configured to be present.

2. The image forming apparatus according to claim 1 , wherein the transferring component is kept being supplied with a transfer voltage while the adjustment image carried by the image-carrying component is passing over the recess.

3. The image forming apparatus according to claim 2 , wherein the recess of the transferring component has such a depth that the adjustment image is prevented from being electrostatically transferred to the recess when the transfer voltage is supplied to the transferring component.

4. An image forming apparatus comprising:
means for carrying a colorant image including an adjustment image;
means for transferring the colorant image from the means for carrying the colorant image to a recording medium in a transfer area while rotating in such a manner as to allow a retainer that is retaining the recording medium to pass through a recess provided in an outer peripheral surface of the means for transferring the colorant image;
means for forming an image that is configured to form the adjustment image at such a position of the means for carrying the colorant image as to face the recess of the means for transferring the colorant image; and
means for transporting the recording medium in such a manner as to cause the recording medium retained by the retainer to pass through the transfer area, wherein
the retainer that is transporting the recording medium while retaining a leading end of the recording medium is configured to be received by and come out of the recess of the means for transferring the colorant image,
the retainer is attached to the means for transporting the recording medium and is configured to go into the recess while the means for transporting the recording medium is moving,
the adjustment image is formed at such a position of the means for carrying the colorant image as to face the recess with the retainer being positioned in the recess, and
the means for forming the image is configured to form the adjustment image to overlap with an area of the recess excluding areas where the retainer is configured to be present.
